specification.

In the description of the said inventio which follows, reference is made to the accompan'ying drawings forming a part hereof, and in which Figure l is an exterior side view of the apparatus. Fig. 2 is an exterior end view of the same,looking in the direction indicated by the arrow. Fig. 3 is an enlarged section of Fig. 1, taken on the dotted line 00 00.

Referring to the drawings, A is a tank or reservoir for holding melted pitch to be used in treating barrelsor kegs.

B is a furnace of any appropriate construction, for super-heating steam to be used as a velhicle for distributing pitch within the barre s.

O is a steam pipe leadingfrom aboiler, not shown, and it passes through the furnace B in the form of a coil which is shown in dotted lines in Fig. 1.

D D are pipes leading from the bottom of the pitch tank or reservoir A having cocks at and discharge nozzles 11. As both the pipes D and their connections are the same, only one complete pitching apparatus will be described although two are shown.

E is a pitch holder consisting preferably, of a piece of ordinary pipe having heads a screwed thereon.

F is a cock connected to the upper head 0 of the holder E, and G a funnel'extending from the cock F and situated directly under the nozzle 1) of the pipe D.

The cocks at and F have arms respectively denoted by e and f connected by a link 9 which effects their common movement, and the link g is provided with a handle hwhereby both cocks are simultaneously opened and closed.

The steam pipe 0 after leaving the furnace is turned down, and then passed along horizontally in the rear of the tank A and provided with branches i, one being for each pitching apparatus. In each branch is a T whereby it is connected to the pitch holder E and at each side of the T is a cockj and These cocks have arms Z and m united by a link 12 which is operated by a lever o and a handlep. The extreme end of the branches 2' of the steam pipe 0 is provided with a rose or sprinkling head Hi I I is a bench upon which the barrels to be pitched are placed.

The barrels or kegs are shown in dotted lines in all the figures.

Fire being in the furnace, and the tank A supplied with liquid pitch, the operation of pitching a barrel is as follows: The cocksj and k are closed, and the cocks at and F opened, which allows melted pitch to enter the funnel G, pass down through the cock F and fill the holder E and the branch pipe 11 between the cocksj and it. As soon as the pitch rises to the top of the funnel the cocks at and F are closed. The barrel or keg is now placed over the rose head or nozzle H and the cocksj and is simultaneously opened. The super-heated steam then drives all the pitch from the holder and the branch pipe, to the interior of the barrel in the form of fine spray, which completely coats the inner surface of the barrel. As soon as the holder is exhausted of its pitch, the cooks j and k are closed and the barrel removed, and placed in the ordinary barrel rolling machine. The process as described is then repeated with a fresh barrel.

Old pitched barrels may be cleansed by using steam alone, the holder being empty.

I claim as my invention- In an apparatus for pitching barrels, the combination of a reservoir for pitch having a discharge nozzle and a controlling cock, a
